Hello!!
I am testing this example: https://es.mathworks.com/help/symbolic/solve-partial-differential-equation-of-nonlinear-heat-transfer.html
The problem is that I am having this error: Unrecognized function or variable 'pdeCoefficients'.
I do not understand why MATLAB is not recognizing this function when I have installed the corresponding toolbox: Symbolic Math Toolbox (Version 8.6)
Can anyone help me find the solution?

Hi!
The version number you have provided refers to MATLAB R2015b. However, the function pdeCoeffecients was introduced in R2021a and will not be accessible by Symbolic Math Toolbox (Version 8.6). The release information for a particular function can be found at the end of the relevant documentation.
You can resolve this error by installing the latest version of the toolbox.
